(1) Material: ①DDQ (deep drawing quality) material: refers to a material for deep drawing (Wash) use, that is, we called the soft material, the main characteristics of this material is higher elongation (≥53 %), low (≤170%) hardness, internal grain grading between 7.0 to 8.0, deep drawing excellent performance. Many production thermos pot business class Guancheng stainless steel cord Which promotions, processing their products generally are higher than (BLANKING SIZE / products in diameter), their processing ratios of 3.0,1.96,2.13,1.98 . SUS304 DDQ timber is mainly used for processing these requests higher than that of the product, of course, working ratio of more than 2.0 products are generally subject to few the stretch to complete. If the extension of terms of raw materials can not reach it, in the processing of deep-drawing products product easy to crack, pull through the phenomenon, affecting the rate of qualified products, of course, will increase the cost of manufacturers; ② general material: mainly used in addition to DDQ material applications outside the characteristics of this material are relatively low elongation (≥45%), while relatively high hardness (≤180), internal grain grade at 8.0 to 9.0, compared with DDQ timber, it Drawability relatively marginal, it is mainly used in the products can be obtained without thrust, like a kind of tableware spoon, spoon, fork, electrical appliances, steel pipe uses. But it is compared with DDQ material has the advantage that BQ relatively good, mainly due to a slightly higher because of its hardness. Stainless steel cord its excellent corrosion resistance to the grain boundary, in the case without heat treatment, but also to maintain good corrosion resistance. 304 stainless steel cord: a good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping, bending and other thermal processing, and no heat treatment hardening. Uses: cutlery, cupboards, boiler, auto parts, medical equipment, building materials, food industry 310 stainless steel cord: The main features are: high temperature stainless steel cord, the general use of the boiler, automobile exhaust pipes other performance in general .303 stainless steel cord: by adding a small amount of sulfur and phosphorus to more than 304 cutting, and 304 others with similar properties. 420 stainless steel cord: "cutting class" martensitic steel, similar to Brandt's first high-chromium stainless steel this. Also used in surgical tools Guancheng stainless steel cord where the good, can do very light. 430 stainless steel cord: PR ferritic stainless steel flexible wire contact, decorative, such as for car accessories. Good shape, but heat resistance and corrosion resistance worse.
